Brilliant
In my opinion this unit performs better than many more expensive changers. Easy to use , automatic charging cycle so no worries about over charging, looks to be well constructed and resistant to damp, just as well in the UK, no need to disconnect the battery from the vehicle.

Good value @ easy to use.
Charger is well made, easy to use @ efficient. Good value. Instructions could be better for people who are not used to using chargers.

Fantastic quality
Purchased to trickle charge my 130Mah caravan battery over winter. I wanted a premium brand charger at a sensible price and this has ticked all the boxes. The only problem is the instructions are a bit bland. The hanging hook is a great addition as well

Easy to use, functional
Easy to use. It allows my wife to keep her car battery charged without having fear. The item comes with two connector types, clamps and ring-terminal and both connect to the charger via a fool proof plug arrangement. For maintenance install the ring terminals and lead the plug to an easy accessible position. The charger can then be plugged and unplugged without fear of making errors or creating a short. Programming is clear and simple. It charges well and the display is reasonably well readable. Built quality seems ok….it’s a sturdy plastic box Previous experience with old Ring chargers were good….tbc

Easy use and reasonable price
Great product bought a 2nd unit however would be good if could get spares I.e. the ring terminals so as easy to connect a trickle charger. The unit its self seem well built and easy to use I like the hook built into the back would also be good if it came with a case instead of a box or at least you could purchase one I.e NOCO.
